# 钟南山 队 发展 Quick and convenient detection reagents #: Blood can be tested in 15 minutes and the results are available] A reporter from Guangzhou Daily reported from the First Affiliated Hospital of Guangzhou Medical University and the Guangzhou Institute of Respiratory Health that the team of Academician Zhong Nanshan and the respiratory infection expert at the hospital Ye Feng's group recently published a paper online in the Journal of Medical Virology, describing for the first time the development of SARS-CoV-2 IgM-IgG combined antibody detection reagents and its application in the clinical diagnosis of new crown virus infectious diseases.
According to reports, the test reagent can be tested only by dripping blood, and the result can be obtained in about 15 minutes, greatly reducing the detection time (the viral nucleic acid RT-PCR test takes 3-4 hours to produce results). Multi-center clinical specimen testing and evaluation confirmed that the sensitivity of the test reagent for clinical detection is as high as 88.66% and the detection specificity is 90.63%; the sensitivity of the IgM-IgG combined antibody test is much higher than that of IgM or IgG single antibody test (94.83% vs 1.72% and 3.45%). In addition, the antibody detection reagent used fingertip blood and venous blood test results for comparison, and found that the consistency of the two detections basically matched; suggesting that the SARS-CoV-2 IgM-IgG combined antibody rapid detection kit can be used as an instant detection ( POCT). Blood can be collected at the bedside with your fingertips for examination. This heralds a more convenient screening approach.
